Abstract
一种用于光伏汇流箱的预警装置，可实现实时监测汇流排接点接触是否良好。光伏汇流箱产业中，由于箱内各铜排接点接触不良，未得到及时处理，酿成大祸的事故事故时有发生。本实用新型的原理在每个汇流排接点附件安装温度传感器，温度传感器实时监测汇流排接点温度，当有接点温度异常时，及时发出报警，通知维护人员处理故障，防止事故影响扩大。这是一个低成本的预警装置，可以及早告知工作人员故障位置，及时高效地处理故障。
An early warning device for a photovoltaic combiner box, which can realize real-time monitoring of whether the contacts of the busbar are in good contact. In the photovoltaic combiner box industry, due to the poor contact of the copper bars in the box, they have not been dealt with in time, and accidents that have caused catastrophe have occurred from time to time. The principle of the utility model is to install a temperature sensor at each junction of the busbar. The temperature sensor monitors the temperature of the junction of the busbar in real time. When the temperature of the junction is abnormal, it will send an alarm in time to notify the maintenance personnel to deal with the fault and prevent the expansion of the impact of the accident. This is a low-cost early warning device, which can inform the staff of the location of the fault early and deal with the fault in a timely and efficient manner.
Description
Skill wood field
The utility model belongs to the field of photovoltaic power generation in the new forms of energy, is the prior-warning device of realizing that monitoring bus-bar contact in real time is whether good.Confluxing here is meant multichannel photovoltaic group string or assembly parallel connection.
Background technology
Single photovoltaic module generated energy generally has only several hectowatts, and voltage has only tens volts.Photovoltaic plant is that parallel connection improves electric current then by the series connection raising voltage of many photovoltaic modulies.The parallel connection here is referred to as photovoltaic here and confluxes.The box that confluxes, header box or direct current cabinet that photovoltaic confluxes and generally is arranged in photovoltaic plant are indispensable parts in the photovoltaic plant.
In photovoltaic confluxes, the reason of a lot of fault generating contact that to be bus-bars among Fig. 1 (among Fig. 1 13) is connected with Fuse box (among Fig. 1 10) or connection terminal (among Fig. 1 12) position loose contact, the contact resistance change is greatly; Electric current through the time, contact (among Fig. 1 12) heating produces very high temperature; This can't carry out artificial judgment unusually basically, and during unmanned for a long time the processing, temperature continues to raise; Burn header box, cause major accident.Because connecting point position is hidden; Be difficult to distinguish whether contact well by naked eyes; The existing goods producer of confluxing does not have good way to this; Can only require the operator in strict accordance with technological process production through the various means of productions, but can not avoid poor contact phenomenon, this accident still happens occasionally.
Summary of the invention
For solving, the present invention proposes and a kind ofly rely on real-time monitoring bus-bar temperature to judge whether to occur the prior-warning device of loose contact owing to the serious consequence that causes can not be in time handled in loose contact.
The utility model solves the technical scheme that its technical matters adopted: the utility model is made up of one or more temperature sensors and the controller that is attached thereto; Temperature sensor is installed in bus-bar and fuse, terminal box or connection terminal tie point next door (shown in accompanying drawing 2); Controller is monitored the temperature of corresponding contact in real time through each temperature sensor; Whether controller is unusual according to each contact temperature that records, and judges whether the contact of loose contact, sends warning message as required; The site administrator can find position of failure point rapidly according to warning message, fixes a breakdown.In order further to improve the accuracy of judgement degree, can be at the local mounting temperature sensor far away slightly apart from contact, as the whether unusual reference of contact next door temperature.The utility model can be realized separately, also can be integrated in other equipment that close on, in the current monitoring equipment that confluxes.Certainly, this device not only can be used to monitor the bus-bar contact, and other that can be used for also that photovoltaic confluxes need be monitored the contact of contact situation.
The beneficial effect of the utility model is: the present invention reports to the police to abort situation through increasing near one or more temperature sensors that are installed in the bus-bar early, and the indication fault position, can improve reliability greatly to fault.
Description of drawings
This instructions has two accompanying drawing: Fig. 1, the contact synoptic diagram of traditional header box bus-bar, and wherein 10 is Fuse box, 11 screws, 12 contacts, 13 is bus-bar; Fig. 2, the contact synoptic diagram of the header box bus-bar of increase monitoring contact fault, wherein 20 is Fuse box, and 21 is screw, and 22 is contact, and 23 is bus-bar, 24 is temperature sensor.
Embodiment
Fig. 2 is the contact synoptic diagram that increases the header box bus-bar of monitoring contact fault, and temperature sensor (among Fig. 2 24) is installed on (or on bus-bar) near the contact (among Fig. 2 22) of bus-bar (among Fig. 2 23), and temperature sensor connects controller, in real time monitor temperature.When the contact loose contact, contact temperature raises, and temperature conduction is to temperature sensor; Controller obtains the temperature of corresponding contact; Whether be abnormal temperature, if abnormal temperature then sends warning message and informs that main control room has branch road unusual through software algorithm if drawing; Notify the maintainer to carry out fault handling, fault was solved before major break down takes place.
